Company X is a leading insurance company which provides laptops to all employees for their work, regardless of their grade in the organization’s hierarchy.
The company has deployed a gateway firewall, incorporated with a DNS filter to blacklist or whitelist access to certain websites. In this manner, users are denied access to malicious websites, and threats due to unauthorized website use is prevented while users are within the office network.
How DNS Filtering Works?
Whenever a user makes an internet search, a request is passed on to the network through an IP. However, when DNS filtering is implemented in an organization, the relevant web page is redirected to the firewall where the restrictions are verified. If it has been blacklisted, access to the webpage is blocked.
Loophole Causing Security Concern
When more and more users beginning to work from home or work while travelling using the laptops provided by the company, Company X began facing new security concerns.
Although the firewall’s DNS filter was effective when users were within the office network, the user’s laptops were outside of the firewall’s reach. This meant that users could access any site or download any software without any restrictions, exposing the company-owned devices (COD) at risk due to unauthorized websites. This, in turn, threatened to compromise both the devices and the data stored in them.
It also made the devices non-compliant to the Company Owned Device (COD) policy.
Prognosis
The DNS filtering rules set by the company no longer applied when users took their devices outside their network and firewall. Addressing this issue, CloudNow’s Identity and Access Management (IAM) solution was deployed. With its website filtering feature, maintaining DNS filter rules was made possible, even outside the firewall.
With Akku, requests made by users to access any website goes through its DNS filter, which checks for restrictions and blocks unauthorized web pages. Here, the router acts only as the connecting bridge to the internet. This makes it possible to maintain website blocking instructions for devices, disregarding where the users access them from through the internet.
Why is DNS Filtering Outside your Firewall is a Necessity?
It is a vital for all organizations to increase the security of their data by preventing access to malicious websites in CODs. Additionally, this feature ensures that all CODs comply with security standards and remain audit-ready.
Maintain your DNS filter rules even outside your office premises with AKKU’s website filtering feature.
